Right, lets stick with that then.

Buck works just as well. The inverter is buck by default.
With a mirrored supply, the ground is floating when the converter is operating. When not, a reverse diode across the capacitor completes the path. The output will be Vbat - 0.7, just like in a boost converter.

In case of a failure on the power switch, the input gets shorted to the output trough the inductor rather than shorting the supply.


Ignore the 3 IGBT's idea. Just me thinking out load.
